The only laptop I would consider upgrading to from my Thinkpad X220 would either be a modern Thinkpad x270 (just for a hardware upgrade because I like the form factor) or to something that provides a similar keyboard, docking, and modern-ish hardware.<p>Most of my work happens over SSH, my laptop is currently fast enough for Netflix, email, and web browsing. I'm capped at 2 1920x1080 monitors but this is livable.<p>I think if someone took the old X220 generation Thinkpads, upgraded the internals, and kept the keyboard and docking that they would sell like hotcakes.
